Hard Anodizing difficult castings to specification
A major international OEM had a high volume cast aluminum part that required type III hard coat anodizing to resist wear.
Their previous supplier provided parts that not only fell short of meeting the thickness specification, but also came at a premium price
The parts are made of 380 cast aluminum, which is a very difficult material to anodize with the difficulty compounded
by almost a two mil nominal thickness requirement. Anodizers throughout the country had all fallen short of achieving
the desired thickness at the target price. With their strong engineering team, high volume and technically
challenging automotive experience, Greystone was drawn to the challenge.
The experience Greystone has with difficult plating opportunities quickly paid off in establishing conditions that duplicated the
current supplier's product; going beyond this and economically achieving the customer's specification was the primary focus of
our efforts. Numerous trials with different chemistries, multiple rectifier profiles, temperature variations, and even several novel
rack configurations were conducted. As with Edison and his light bulb, more ways were found to miss the target than to hit it, but
eventually Greystone isolated the parameter to achieve the desired thickness.
Simultaneously Greystone set to work developing automated equipment to facilitate optimized handling
procedures and minimize labor costs.
The ultimate solution was a creative combination of several elements. The rack design, rectifier control, pre-treatment regiment,
as well as the anodizing bath chemistry all factored into achieving the desired end product. Greystone not only produced a
consistently thick coating to specification, but also exceeded the customer's price target.
